Serpent SER500900 13mm Shock Piston Blank  [SER500900]

13 mm piston core for 13mm shocks

This Serpent SER500900 Shock 13mm piston blank is an RC-scale piston core designed for 13mm shock absorbers in model car dampers. The blank acts as a base piston that pairs with compatible shock bodies and shim stacks to control fluid flow and refine damping behavior.

Compatibility: intended for shock assemblies with a 13mm internal diameter; match the piston to your chosen shock oil viscosity, shaft diameter, and any holeing or shim arrangements while tuning. Do not assume fitment with non-13mm systems without confirming actual dimensions.

Installation notes: examine the piston blank for machining burrs before installation, keep piston orientation consistent across pistons in the same damper, and use the correct retaining hardware and O-rings for your shock. After assembly, cycle the shock to eliminate trapped air and confirm smooth shaft travel prior to running.

Tuning role: the blank provides a neutral flow baseline; replacing it with drilled or ported pistons or altering shim stacks changes compression and rebound. Use the blank when developing progressive valving or when you want to restrict flow to raise damping resistance.

This component is a basic piston element for RC dampers, handy during iterative shock setup and when creating custom piston arrangements.
